As a fast-growing company, AMPERA blends the agility of a startup with the ambition of a global energy innovator. Joining us means becoming part of a bold mission to revolutionize how the world generates power through advanced simulation, multiphysics modeling, and nuclear innovation.
Position Overview
AMPERA is seeking a talented Simulation & Modeling Engineer to develop and execute advanced computational models that simulate the behavior, performance, and safety of AMPERA’s hybrid nuclear micro-reactor systems. This position plays a central role in integrating physics-based simulations across neutronics, thermal-hydraulics, materials behavior, and structural mechanics to optimize system design and performance.
The ideal candidate has strong experience in multiphysics modeling, numerical methods, and high-performance computing (HPC), along with a deep understanding of reactor physics and engineering systems.
Key Responsibilities
- Develop coupled reactor physics, thermal-hydraulics, and structural simulations using tools such as COMSOL, Abaqus, or OpenFOAM.
- Perform sensitivity, uncertainty, and parametric analyses to guide design decisions.
- Integrate simulation results into system-level digital twins for design and operational prediction.
- Collaborate with nuclear, mechanical, and materials engineers to validate models with experimental and prototype data.
- Support design verification and safety case development through simulation-based evidence.
- Develop custom modeling scripts and workflows in Python or MATLAB to automate analysis and visualization.
- Contribute to the verification and validation (V&V) framework for multiphysics modeling tools.
- Prepare technical documentation, results summaries, and presentations for internal and regulatory review.
Qualifications
- M.S. or Ph.D. in Nuclear Engineering, Mechanical Engineering, Applied Physics, or related field.
- 5–10 years of experience in advanced simulation, modeling, or computational analysis.
- Expertise in multiphysics coupling, CFD, and finite element analysis (FEA).
- Proficiency in modeling software such as COMSOL, Abaqus, or OpenFOAM.
- Experience with HPC environments, scripting languages (Python, MATLAB), and data visualization.
- Familiarity with reactor design principles, radiation transport, and safety analysis.
- Excellent problem-solving, collaboration, and communication skills.
- U.S. citizenship or eligibility for security clearance may be required.
What We Offer
- Competitive salary.
- Comprehensive benefits package including healthcare, dental, vision, and 401(k).
- Opportunity to work on cutting-edge reactor simulations that define the future of nuclear energy.
- A collaborative, innovation-driven culture committed to technical excellence.
- Significant career growth potential as AMPERA advances its modeling, testing, and reactor deployment programs.
